Description

Technical Field

[0001] The present invention belongs to the technical field of video tracing, and in particular relates to a method, system, device and storage medium for tracing video of agricultural products. Background Art

[0002] With the advent of the digital age, the agricultural sector is undergoing unprecedented changes, especially in the traceability of agricultural product quality and the building of consumer trust. Food safety and quality transparency have become the focus of modern society, and consumers have put forward higher requirements for the production process and source information of agricultural products. In this context, agricultural product traceability technology, as an emerging and effective means, is gradually occupying an important position in the field of agricultural product quality management. At present, agricultural product traceability technology has also made certain progress, and a variety of traceability solutions have emerged on the market. Most of these solutions are based on blockchain, RFID, Internet of Things and other technologies, and realize a certain degree of traceability of agricultural products by storing and transmitting key information such as production, processing and transportation of agricultural products. However, these technologies still have many defects in practical applications. Defect 1: Low credibility of traceability evidence. Blockchain + picture traceability technology utilizes the decentralized and tamper-proof characteristics of blockchain to store the picture information of agricultural products on the blockchain to realize the traceability function. However, this technology relies only on static pictures and cannot provide intuitive evidence in the form of video, so it cannot fully reflect the dynamic production process of agricultural products. Defect 2: High platform construction cost. Internet of Things + video surveillance technology allows some Internet of Things platforms to install video surveillance equipment to monitor the production environment of agricultural products in real time. Although this method can provide richer video data, the technology usually requires the installation of fixed video surveillance equipment in specific locations (such as workshops), resulting in high initial construction costs. In addition, it mainly focuses on the monitoring of the production environment rather than the specific packaging and sorting of agricultural products. At the same time, due to the large amount of video data, the high storage and transmission costs also limit its wide application in the traceability of small batches of agricultural products. Defect three: lack of one-to-one traceability technology. In the current agricultural product traceability system, the traceability of large quantities of agricultural products often becomes the focus. The traceability process of large quantities of agricultural products often encounters technical bottlenecks and cost pressures due to massive data processing requirements and complex system maintenance. At the same time, this large-scale processing method cannot provide unique traceability information for each piece of agricultural product, resulting in a significant reduction in the traceability effect.

[0070] Example 1

[0071] Additional aspects and advantages of embodiments of the present invention will be given in part in the following description and in part will be obvious from the following description or learned through practice of embodiments of the present invention.

[0072] Combination Figure 1-Figure 7 The embodiment of the present invention provides a method for tracing the source of agricultural products through video, comprising:

[0073] S1: Collect agricultural product traceability data through the data collection terminal and store them in different storage modules by category. Agricultural product traceability data includes: video data of agricultural product packaging process, basic information of agricultural products and operation records. Basic information of agricultural products includes production date, origin and quality inspection report of agricultural products.

[0074] S2: After data storage is completed, a data index is established based on video data, basic information of agricultural products and operation records.

[0075] S3: Perform data verification and encryption on the agricultural product traceability data to obtain encrypted agricultural product traceability data.

[0076] S4: Process and associate the encrypted agricultural product traceability data, and store the associated information data in a database.

[0077] S5: Scan the QR code on the agricultural product packaging to jump to the H5 page and obtain the related information data of the agricultural product.

[0078] Specifically, step S1 collects agricultural product traceability data through a data collection terminal and stores it in different storage modules by category, including:

[0079] S11: The video data of the agricultural product packaging process shot in real time on site is collected by a mobile camera, and the basic information and operation records of the agricultural products are obtained by scanning the QR code on the agricultural product packaging through a PDA handheld terminal.

[0080] S12: The video data and basic information of agricultural products are stored in the server and database respectively, and the operation records are stored in the blockchain.

[0081] In an embodiment of the present invention, the mobile camera uses a head-mounted camera of model DS-MCH208 / 32G / GLE. Before collecting data, the DS-MCH208 / 32G / GLE head-mounted camera needs to be connected and configured with the PDA handheld terminal through a dedicated interface or wirelessly. A dedicated data acquisition APP is installed on the PDA handheld terminal. The APP needs to support receiving video stream data from the DS-MCH208 / 32G / GLE camera and have the functions of data storage, preview, editing and uploading to the data storage system. The camera device is identified and configured through the APP, including setting parameters such as video resolution and frame rate, as well as network configuration, to ensure that the PDA handheld terminal is connected to a stable Wi-Fi network, or to enable a mobile data connection to facilitate remote data transmission. Because it is also necessary to remotely transmit to its corresponding storage area, it is also necessary to configure a corresponding VPN or secure channel to ensure data security. After completing the parameter configuration, on the one hand, the video recording function in the data acquisition APP of the PDA handheld terminal is started. The staff uses the head-mounted camera to shoot the video of the packaging process of agricultural products in real time, and transmits the video stream to the PDA handheld terminal. The APP on the PDA handheld terminal is responsible for receiving, previewing and temporarily storing video data. The data acquisition APP on the PDA handheld terminal can perform preliminary processing on the recorded video, such as cropping, rotating, and marking. The processed data can continue to be stored on the PDA handheld terminal, or directly perform the next transmission operation. On the one hand, the PDA handheld terminal scans the QR code on the agricultural product packaging box to obtain the basic information and operation records of the agricultural products. The basic information of agricultural products includes the production date, origin and quality inspection report of the agricultural products, and then uploads the collected video data and picture data to the corresponding storage area through Wi-Fi or mobile data network. During the upload process, the security and integrity of the data need to be ensured, and encryption transmission, checksum and other mechanisms can be used. The present invention uses a high-definition camera to collect video data of the final packaging link of agricultural products in real time, and transmits the data to the corresponding storage area in real time through a wireless network or a wired network for storage and analysis, which can ensure that the data in the final packaging process of agricultural products is collected and transmitted in real time, accurately and completely, and provides reliable data support for the traceability system. Among them, the video data is stored in the server, which is responsible for the storage and management of video files and has high throughput and stable network connection. The basic information of agricultural products is stored in the database. The embodiment of the present invention uses a high-performance rack server and configures sufficient CPU cores, memory and I / O channels to support high concurrent data processing requirements. The operation records are stored in the blockchain. The present invention stores the operation records of each agricultural product in the blockchain and uses blockchain technology to store the traceability information of agricultural products in the form of blocks. Each block contains the hash value of the previous block to ensure the integrity and non-tamperability of the data.

[0082] Specifically, after completing the data storage in step S2, a data index is established based on the video data, basic information of agricultural products and operation records.

[0083] The present invention facilitates subsequent data query and retrieval by creating indexes for stored data.

[0084] Specifically, step S3 performs data verification and encryption processing on the agricultural product traceability data, and the encrypted agricultural product traceability data obtained includes:

[0085] S31: Perform format verification and integrity verification on the video data, and perform field verification on the basic information of agricultural products and operation records.

[0086] The present invention performs format verification and integrity verification on video data to ensure that the data is correct before storage, and performs field verification on basic information of agricultural products and operation records to prevent invalid or erroneous data from being stored. The verified data is written into a storage device, and the data access efficiency is optimized using indexing, partitioning and other technologies.

[0087] S32: Encrypt the verified data to obtain encrypted agricultural product traceability data.

[0088] The embodiment of the present invention encrypts data and stores sensitive data in encrypted form to protect the data from unauthorized access. In addition, the storage device and network environment are scanned regularly to discover and repair potential security vulnerabilities. An access control mechanism is established to strictly control data access rights and ensure that data is accessed only with legal authorization.

[0089] Specifically, step S4 processes and associates the encrypted agricultural product traceability data, and stores the associated information data in a database, including:

[0090] S41: Parsing the corresponding agricultural product identifier and anti-counterfeiting code from the operation record and generating a QR code, wherein the agricultural product identifier includes the batch number and serial number of the agricultural product.

[0091] The embodiment of the present invention parses the operation records to extract unique identifiers related to agricultural products, such as batch numbers and serial numbers of agricultural products, and configures a unique anti-counterfeiting code for each agricultural product. A unique QR code is generated based on the agricultural product identifier and the anti-counterfeiting code to ensure the uniqueness and anti-counterfeiting nature of each agricultural product. Consumers can verify the authenticity and production information of the product by scanning the QR code.

[0092] S42: Perform multi-threaded video encoding and compression processing on the video data to obtain video processing data.

[0093] The embodiment of the present invention uses FFmpeg open source video processing tool to perform multi-threaded encoding and compression processing on video data, and adjusts the encoding parameters according to actual needs to achieve the best compression ratio and image quality balance. By performing multi-threaded video encoding and compression processing on video data, the storage space and transmission bandwidth requirements of video data are greatly reduced, thereby reducing storage and transmission costs. Among them, FFmpeg open source video processing tool is a powerful multimedia processing tool set that can process all types of audio and video data, including encoding and decoding, format conversion, transcoding, streaming, filtering and playback.

[0094] S43: Divide the video processing data into a plurality of video segments corresponding to each operation node in the operation record according to the time period, and assign a corresponding video identifier to each video segment.

[0095] S44: Associating the video identifier of each video clip with the corresponding agricultural product identifier, anti-counterfeiting code and basic information of the agricultural product, and storing the associated information data in a database.

[0096] The present invention divides the video data into multiple traceability video clips uniquely associated with the agricultural products according to the time period, assigns a unique video identifier to each video clip, then associates the unique identifier of the video clip with the unique identifier of the agricultural product, and stores the associated information data in a database for subsequent query and tracing. In a specific embodiment of the present invention, the video acquisition action is triggered at the key node of agricultural product production, and the unique identifier of the video clip is associated with the unique identifier (QR code) of the agricultural product, ensuring that each agricultural product has unique video traceability information, and realizing the traceability management of the whole chain.

[0097] Specifically, step S5 jumps to the H5 page by scanning the QR code of the agricultural product packaging to obtain the related information data of the agricultural product.

[0098] In an embodiment of the present invention, the H5 page provides consumers with a convenient traceability query entry. Consumers can jump to the H5 display page by scanning the QR code on the agricultural product packaging box, and can watch the packaging video of the agricultural product, and can also view the detailed traceability information of the agricultural product, such as production date, origin, quality inspection report, etc. The H5 display page relies on a Web server. The present invention selects a high-performance Web server, such as a server equipped with a multi-core CPU, a large-capacity memory, and a high-speed SSD, to ensure that a smooth user experience can be maintained during high concurrent access. The present invention uses front-end technologies such as HTML5, CSS3, and JavaScript to develop H5 pages to ensure that the page has good cross-platform compatibility and user experience. The designed H5 page layout includes a top navigation, a video player area, an information display area, etc., to meet the traceability query needs of consumers. The H5 display page also has a code scanning query function. It listens to code scanning events through JavaScript (usually implemented by calling the code scanning APP or browser plug-in on the device), and parses the URL or data in the QR code to achieve interface docking with the data storage module. It calls the API interface provided by the data storage system through technologies such as AJAX or Fetch API to obtain detailed traceability information of agricultural products. The H5 page is also equipped with a data storage system interface, which is used to query the traceability information of agricultural products from the database, blockchain and server by defining a set of RESTful API interfaces. The interface contains necessary parameters (such as product ID, query key) and returns data in JSON format. For example, consumers use the code scanning APP on smartphones or the built-in code scanning function of the browser to scan the QR code on the packaging box of agricultural products. The QR code contains a URL pointing to the H5 page or a query parameter in a specific format. After receiving the code scanning request, the H5 page parses the information in the URL or query parameter, and calls the data storage system interface to obtain the traceability information. After the page is loaded, the packaged video of the agricultural product (if the video file is embedded or can be accessed through the URL) and detailed traceability information are displayed.

[0125] Furthermore, an embodiment of the present invention also provides a computer-readable storage medium, in which a computer program is stored. The computer program is loaded and executed by a processor to implement the above-mentioned agricultural product video traceability method.

[0126] Furthermore, an embodiment of the present invention also provides a computer program product, which, when executed on a data processing device, is suitable for executing a program that initializes the steps of the agricultural product video traceability method as described above.

[0127] In summary, the agricultural product video tracing method, system, device and storage medium provided by the present invention have the following advantages:

[0128] 1. The present invention integrates video and blockchain technology to achieve real-time video recording and tamper-proof blockchain storage of each agricultural product. This technology makes up for the shortcomings of traditional image traceability in the dynamic process and the lack of personalized traceability. It intuitively displays the dynamic production process of agricultural product packaging in the form of video, greatly improving the credibility of traceability evidence.

[0129] 2. The present invention not only retains the ability of real-time monitoring, but also effectively reduces the cost of platform construction. Using handheld PDAs and head-mounted cameras, these devices are not only low-cost, but also can be flexibly applied to different locations, whether it is in the fields or warehouse sorting sites, they can be easily dealt with. The present invention also particularly strengthens the traceability tracking of the key link of agricultural product packaging, and through multi-threaded video encoding and compression technology, it greatly reduces the storage space and transmission bandwidth requirements of video data, thereby reducing storage and transmission costs, providing strong support for agricultural product video tracing, and ensuring its wide application in small-batch agricultural product traceability.

[0130] 3. The present invention effectively overcomes the technical bottlenecks and cost pressures encountered in large-scale traceability. By combining dynamic video recording with blockchain technology, it can provide accurate and detailed traceability information for each agricultural product, making up for the deficiency of being unable to provide unique traceability information for each agricultural product due to large-scale processing, which greatly reduces the traceability effect.
